$79.99 x 12% = $9.5988 merchandise discounted
$79.99-$9.5988 = $70.3912 rounded $70.39 sales merchandise
$70.39 x 6.75%= 4.7513 sales tax
$70.39 + $4.7513= $75.1413 or
the answer rounded is: $75.14
Answer:
the angles are supplementary. x=20
Answer:
Vectors are not the same as lengths.
Step-by-step explanation:
1. The error is that Vector AB + Vector BC = Vector AC
2. The same thing relates to the second analyses(Vector AD is equal Vector DC)
3. The third is all right.
Answer:
Total Bill = 4006 dollars
Step-by-step explanation:
A cell phone company charges a flat fee of 20 dollars plus 3 cents a call.
If there was a total of 200 calls for the month, the total charge by the cell phone company will be.
Let me convert all to cent first
100 cent = 1 dollar
20 dollar =20 *100
29 dollar = 2000 cent
Charge by the company for a call is 2003 cent
Let me put down the equation.
1 call = 2003 cent
200 calls =( 200 calls* 2003cent)/1 call
200 calls = 200 * 2003cent
200 calls = 400600 cent
Let's convert back to dollar
100 cent = 1 dollar
400600 cent = 400600/100
400600 cent = 4006 dollars
No.
The maximum possible area given a constant amount of material for a quadrilateral will always be a square.
For example if the material for the perimeter is 64 we can form a rectangle that is 22 by 10 which will have an area of 220 u^2.
However a square using the same amount of material will have sides of 64/4=16 and an area of 16^2=250 u^2
So in general the area is maximize the closer the sides are to being equal and minimized as the difference between the sides becomes greater. In the case of comparing the material, perimeter, of a rectangle to a square for the same amount of material the square will use less material than the rectangle.
A square can have a smaller perimeter and a greater area that a rectangle.
In the example above the rectangle had a perimeter of 64 u and an area of 220 u^2. If we made a square with just 60 u, it would have an area of 225 u^2.
